For the record the protesters have no right to block legal access to federal land already approved by the Army Corp of Engineers. On the other hand from the very beginning the government has been blocking Facebook feed from Standing Rock and Green Party members. As for peoples 1st Amendment rights don’t forget that President Obama reminded us ”I don’t need no stinkin Constitution, I’m a Constitutional Lawyer G*d Dammit!’!! To be fair most on the left believe the 1st Amendment was established to protect peoples right to own and make porn and freedom from religion. So it’s a safe bet the ACLU won’t get involved until Trump becomes President.
